kaushik what exact model is your TV?

의 답변

I had the same problem. Did all the simple fixes to no avail. Then I tried tapping the back of the TV and it has been good for a while now. Maybe loose wire or something but worth a try.

의 답변

Kaushik, you have a bad power supply board. Find your part at buyqual.com as I did fixed mine 2 days ago it was doing the exact same thing.

I had this problem after not using me TV for a few weeks...I had my Xbox one plugged into hdmi 2 .Played all night with no problems.The next morning I ran into this problem here being discussed.I tried many things but what worked was me unplugging the hdmi cable.I had noticed that the TV kept a lot of residual energy while it's plugged in...Now I unplug it each time after using and ONLY plug it in now AFTER powering on my TV...

Take a look at this.

4 red blinks- can be LD board or main logic board, check inverter board wires for arcing to ground

6 red flashes- backlight issue, bad main board, or power board or inverter boards- check standby volts on power board. "backlight on" volts should be 3-5v from main logic board then 24v to inverter

Hi Johnny. I'm debugging a kdl46w4100. Initially I replaced the power board because I was not getting standby 3.3V. Now I have 3.3V standby so I'm passed that and so now I have the 6 red flashes. I can see on the connector coming from the main logic board to the power board that the "backlight on" signal goes to 1.8v but not to 3.3. The HV lines (wrapped in double heat shrink) going to the inverter board) never go to 24v - they never do anything. My guess is that the main logic board is not properly telling the power board to send the HV to the inverter board. Ideas? Thanks!

The 6 red blink code on Sony is usually a fail safe on the main board for plasmas... Usually set off by power surges brown outs and dirty electricity, this is done to prevent fires and further component damage so the customer will send the unit into Sony to get its components checked. This is a unique feature for Sony plasmas as they are carrying a high amount of electricity. Google or YouTube Sony Bravia reset. You will need a compatible Sony remote to perform the reset. I have fixed 3 2012 models and one 2011 from the 6 blink code using this method and 3 of those units have been functioning great after 6 months. A lot of repair shops easily misdiagnose it as a power board issue... Guess they don't know how to use google. And there is usually nothing physically wrong with 6 blink tvs it's just Sony trying to cover their ass at the time so there was not a recall since they were losing money on production when the units came out, similar to the PS3. hope this helps you all out ifixit community. - Brandon

Brandon, My Sony 46 inch XBR has a disheartening condition. When plugged in it tries to start - by powering on and the Sony logo at the front bottom of the TV lights up. I've replaced the backlight board and the power board but no luck. Could it be the main board NOT TELLING the rest of the unit what/how to fire up?

How do I get another Main board.

의 답변

I neglected to state that after it tries to power up after about 10 seconds an a few clicking sounds, the Sony logo light goes off and the Standby light begins flashing 6 times, repeating.

의 답변

Mine was the power supply board did the same as you are describing, replaced the power supply board and Wallah TV was working again

의 답변

Most of the time it is the back light. If you want these TV 's to last turn back light setting down to 0. Will look a little dark for a while till you get used to it but no problem for 8 months after I did it. I had back light fixed twice in one month. Lucky it was under warranty. Keeps the heat down. Originally had it on full blast looked very bright.

의 답변

I'm getting the light also 6 flashes. I unplug and plug back in. It turns on and a far right vertical strip flickers and shuts off. I actually got it to turn on after I did the reset and moved it around. Once I tried to switch screens to go to settings the screen flickered and shutoff.

Per Sony site, unplug for 3 minutes if your T.V. picture goes out and you have blinking red lights. If still have a problem and T.V. is plugged into a power strip, then unplug for 3 minutes, then plug directly into wall. The power strip could be bad. (https://us.en.kb.sony.com/app/answers/de...)

It could also be a backlight problem of some sort.

If you can view T.V. again, and want to see error codes, do the following: Turn T.V. off. Quickly press "Display", "Channel 5", "Down Volume", then "Power". Press "Power" again if nothing came up on T.V. See error codes. Press "Power" again, then again, to return to normal T.V. (https://electro-medical.blogspot.in/2016...) and (http://tampatec.blogspot.de/2015/03/sony...)

I have same problem with my T.V., Sony kdl32xbr4. I already know I have a backlight error of some sort, since part of the screen is slightly darker. The codes verified that. I also had the 6 blinking red lights with no picture at all. Unplugging for 3 minutes did reset the picture. Error 6 was listed on my T.V. as a backlight problem. Though I do not know for sure if Error 6 is the same as the 6 blinking lights, since the blinking light happened when the picture went totally out. The backlight partially went out a few month ago with no blinking lights.

I will eventually need to take my T.V. in for repair but do not currently know what the cost will be. I am hoping it is worth repairing. It has been a great T.V.

These units seem the have the same problem with the red light blinking. I had just purchased a new 75 in 800g and after just three days of watching it went out. Was watching a program, and all of sudden, tv shut down and then started blinking. I tried to reset by unplugging and plugged back in and looked like it tried to start, but then that awful clicking noise, and shut off again. I called the store where I purchased the unit and they said they would be sending me a new tv. Just an inconvenience for customers for paying a good price for a decent set and then this happens. You wonder why they would not get on board with this problem and have it done with. Most of these problems seem to arise from the main board. That happened to a Sharp 65 in I had. Still waiting for the part to replace the board. With this problem, I had no sound, but a great picture. Frustrated indeed...

I resolved the issue by solder and ground the pins at the top of the backlight terminal,

Where did you solder at exactly?

의 답변

yes ground what pins of the block,, the already grounded pins, this would mean bad solder joints aka reflow, or bad transistor grounds to backlight i know sony use fail safe software and if such errors happen it shuts down the mainboard ,

I had the same problem on my KDL40 - power on then Green Light followed by SONY logo a couple of times then blank screen with red light blinking six times repeatedly.

Googled Sony problems for 6 blinking reds and got several comments on dodgy power boards or LED strips etc..

Disconnected everything a laid it screen down on the floor and got the Henry Vac to clear all the dust and wiped down the back with baby wipes.

Checked that it was only 4 years old so tried the Reset sequence....

First find the TV power on/of button on the side.

Then plugged in power cord and power on while holding the up arrow button on remote. then with SONY logo pumped on/off button while up arrow held down.

Great News......it came up good as usual saying No Signal so plugged in SKY and selected the SKY Sports channel fine....

Lets hope it stays working and was just a Sony safety shut down, we shall see.

After it comes back to life go to menu and turn back light to zero and it should last. The back light over heats and they start to burn out

I disconnected the Wi-Fi board and the unit fired back up plugged the Wi-Fi board back in and it still works . I will let you know when itvflashes 6 times again. Oh by the way I replaced the power supply board prior to unplugging the WiFi board.

mdurkin, so was it the replacement power supply that fixed your issue or was it the unplugging of your WiFi board?

I haven't got mine figured out. I talked to a repairs hop and he said mine was the led panel and I would have to replace 18 strips or something like that to fix mine. Also that the strips were hard to find and the changing them could cause more issues (cracked screen). I would be interested if there are some other solutions with some pictures to show what they did.
